Improvement in road-scrapers



@sind lteres Letters Patent No. 98,957, dated January 18, 1870.

IMPROVEMENT IN ROAD-SCRAPERS.

The Schedule referred to in these Letters Patent and making part of the same.

I, ROBERT HAMILTON, of Franklin, in ther county of Johnson, and State of Indiana, have invented a certain Road-Scoop or Scraper, of which the following is a specification.

'My invention relates to certain improvements in the;l

road-scraper, patented to me on the 26th da'y of J anuary, 1869; and

The rst part of my invention consists in a device for insuring greater' stiHne-ss and stability in the frame.

The second part of my invention consists in au improved construction of spring-latch, whereby it is adapted for use, either' by the hand or by.the foot, at will. y

Figure 1 is a side elevation of' a scraper embodying my invention, one of the handles being broken oi, and the scoop being shown in section. u

Figure 2 is a' perspective view of thesame, with the scoop disengaged.

The beam4 A, handlesB B', and braces C C of my im provedimplement, are of iron, the beam bein gcurved downward and forward, as shown, so esito dispense with a shethand, in conjunction with the said iron handles and braces, to constitute a frame-work which combines strength with lightness.

The lower end of the beam A terminates in a Tf head, K, whose extremitiesenter ears EE', oil the under side of the scoop D, so as to constitute a hinged connection between the frame and scoop. l

Braces F F', extending obliquely rearward from the extremities of 4the T-head K to the beam, serve to stilien and preserve the parts in their -proper relative positions.

When in use, the rear portion of the implement rests upon a shoe, G.

The open movement of the scoop D is restricted by a chain, H, as in my patent aforesaid. i

The different parts ofthe implement are united' by bolts L and nuts l, the removal of which will permit the detachment of any member of the frame-Work in case a portion `should become broken. ,The nuts lbeing of a uniform size, can all be operated by a single y Wrench, which may be furnished with the implement.

The scoop is caught and held to its eiective position by a spring-latch, I, which is capable of being operated by the foot, as in my aforesaid patent, but is also provided with a hand-trigger, J, wherebythe operator is enabled to liberate the scoop by means of his right hand, without letting go of the handle, it being found that one liberating-device is more convenient to one operator, and the other to another.

The lower end of the beam enters a recessin the shoe G, and is secured therein by traversing bolts.

I claim, as my invention- 1. In the described combination with a beam, A,

handles B B', braces C C', and pivoted scoop D, con- Y structed as represented and described, the T-head K,

ears E E', and Ybraces F F', constructed, arranged, andA i employed as set forth for the purpose shown.

2. In combination with a pivoted scoop, D, the springlatch I J, adapted for operation by foot or hand, as and for the purpose specified.

3. The combined arrangementof the beam A, han

dles B B', pivoted scoop D E E', shoe G, T-head K,

braces C G F F', chain H, spring-latch I J, andfastenings L l, constructed and employed as described,

as and for the purpose set forth,

,In testimony of which invention, I hereunto set my hand.
